I just got my TYC brand euro-lights from eBay. My car is a w201 1992. It seems the plugs in the car have four prongs, while the headlights have 5 on the back of them.
Will the four-prong plugs in my car still fit, or do I need to get new plugs. If I do need new ones, what are the part numbers of the plugs I need to get? By the way, here's a link to what I bought. It claims to have plugs with them, I received these little black things with holes. Are those the correct ones I need?
Please link an installation guide too.
